Observation 151119: Suillus hirtellus (Peck) Snell

When: 2013-11-03

Collection location: Franklin Parker Preserve, Chatsworth, New Jersey, USA [Click for map]

Who: I. G. Safonov (IGSafonov)

No specimen available

These were not in that great of a shape, but nevertheless the key features — namely:

1) Pale yellow pileipellis with reddish-brown fibrils, staining vinaceous from contact/handling
2) Olive-yellow pore surface at maturity
3) Pale yellow stipe with reddish-brown glandular dots
4) Lack of partial veil and annulus

— were still intact and led to a fairly unambiguous ID.

Observed chemical test reactions:
KOH = purplish-brown on cap; brown on flesh
NH4OH = pale purple on cap; greenish-blue on flesh
FeSO4 = grayish-green on cap; mustard-green on flesh

The reference states fruiting occurs through September, so these came in very late. But then the 2013 season was very weird…


NH4OH stain = left; KOH = middle; FeSo4 = right
